What is Web Application Firewall

Last Updated: Sep 21, 2017

Web Application Firewall (WAF) is a dedicated firewall that monitors, filters, and blocks HTTP traffic to and from web applications. By inspecting traffic, the WAF protects the network from attacks through web application vulnerabilities.

As a key component of Alibaba Cloud Security, the Alibaba Cloud WAF applies to most common web attacks, such as SQL injections, XSS, web shell, Trojan, and more. The WAF improves the website performance through HTTP or HTTPS floods mitigation, and bad bot protection. It also provides customized security policies for various scenarios.

Compared with traditional hardware devices, the Alibaba Cloud WAF can be deployed within 10 minutes to protect your web service. It requires no complicated hardware deployment or tedious settings, such as routers and switches.
